Systematic excavations at the Castillo de Huarmey archaeological site, located on the North Coast of Peru, enabled researchers to collect an immense number of fabrics. During the first season of textile investigations, carried out in July of 2014 by American and Polish researchers, 724 objects were examined, including textile fragments, yarns, and cordage. A general description of the basic structures indicates a variety of weaving techniques. Although the collection consists mainly of plain weave of all kinds, new structures such as three-dimensional cross-knit looping and feather-mosaic work were recognized, none of which were encountered among textiles collected from the surface in previous decades.

Peruvian tapestries are prestige textiles, known for their mosaic-like patterns made of multicoloured yarns. Numerous tapestry fragments from the Middle Horizon Period (650-1050 A.D.) were found at the Castillo de Huarmey archaeological site on the North Coast of Peru, where an intact Wari royal mausoleum was discovered. Relying on technological and iconographical analyses and, also on the context of the entire textile collection, a new Middle Horizon tradition associated with the expansion of Wari culture is proposed.
